Mrs. Sterling got so angry that she ran after them. sothat，suchthat：so后面是跟形容词和副词；而such后面是跟名词。 suchthat与sothat都可以用来引导结果状语从句，意为“如此以致”。,suchthat的句型结构可分为以下三种：such +a（n）（+adj.）+单数可数名词+that从句。She is such a good teacher that all of us love and respect her. Table tennis is such an interesting game that people all over the world play it.such（+adj.）+复数可数名词+that从句。如：They are such interesting books that I want to read them once more/again. such（adj.）+不可数名词+that从句。如： It was such bad weather that I had to stay at home.,2）so是副词，与形容词或副词连用，其结构是：so+adj.（adv.）+that从句。He ran so fast that I couldnt catch up with him. I am so sleepy that I can hardly keep my eyes open.,注意当名词前面有many，much，few，little等表示数量多少的限定词时，应该用so，而不能用such。There were so many people in the street watching the fire that firefighters could not get close to the building. 当单数名词前有形容词时，既可用so，也可用such，但不定冠词的位置却有所不同。This is such an important meeting that you should attend it.（=This is so important a meeting that you should attend it.）这是一次很重要的会议，你一定要参加。,5、She was soon out of breath, but she continued to run.out of breath Tom ran to the shop to get some salt for his mother.
